Pirate Galaxy Overview

Pirate Galaxy

Pirate Galaxy is a free to play 3D Sci-Fi mmog, which is browser-based, but you can optionally download a small client for an enhanced graphics experience.

You control a spaceship, and you have to fight against the evil alien race called Mantis, to save the humanity. By completing missions, you earn crystals which can be spent to purchase new parts for your spaceship, or even a new spaceship (there are a lot available).
